Ed Sheeran & Justin Bieber’s ‘I Don’t Care’ Hits No. 1 On Pop Songs Airplay Chart

Plus, Taylor Swift's 'You Need to Calm Down' reaches the top 10.

Ed Sheeran and Justin Bieber's "I Don't Care" hits No. 1 on Billboard's Pop Songs radio airplay chart dated July 27.

The track (released on released on SchoolBoy/Raymond Braun/Atlantic/Def Jam) is Sheeran's fourth Pop Songs No. 1, after "Thinking Out Loud" (one week, 2017), "Shape of You" (nine, 2017) and "Perfect" (three, 2018).

Bieber banks his sixth leader, following "What Do You Mean?" (two, 2015), "Sorry" (three, 2016), "Love Yourself" (five, 2016) and two tracks via featured roles, on Major Lazer's "Cold Water," also featuring MO (one, 2016), and Luis Fonsi and Daddy Yankee's "Despacito" (five, 2017).

The Pop Songs chart measures total weekly plays, as tabulated by Nielsen Music, among its reporting panel of 167 mainstream top 40 stations.

"Care" makes history as the first Pop Songs No. 1 (among 370 since the chart's 1992 inception) credited solely to two co-billed male soloists that don't regularly record together. Still, it follows No. 1s by two male leads joined by other acts, including "Despacito" and, in March, "Eastside" by Benny Blanco, Khalid and Halsey. Two songs by three lead males have topped the tally: "Shake Ya Tailfeather," by Nelly, P. Diddy and Murphy Lee in 2003, and "All for Love" by Bryan Adams, Rod Stewart and Sting in 1994 (a month before Bieber was born).

"Care" is from Sheeran's album No.6 Collaborations Project, which launches as his third No. 1 on the Billboard 200.

Plus, Taylor Swift's "You Need to Calm Down" rises 11-10 on Pop Songs, becoming her 18th top 10. She ties Justin Timberlake for the fourth-most top 10s, after Rihanna (30), Maroon 5 (20) and P!nk (19).
